Een nevel in de Melkweg
by Lathish ShankarAmelia, een studente, staat open voor paranormale gebeurtenissen. Ze schreef ooit een artikel voor haar universiteitsmagazine waarin ze zegt dat ze soms stemmen uit de toekomst hoort. Stephen, de hoogleraar natuurkunde leest het artikel en bespreekt dit met zijn vrouw Isabella. Isabella zegt dat Amelia haar patiënt is, die lijdt aan bloedfobie. Dit was de reden waarom ze het zoölogielab en de dissectieklas overslaat. Ze werd opgenomen in haar ziekenhuis nadat ze flauwviel in de kantine, terwijl ze ijs at met haar vrienden Rosemary, Merlin, Prince en Neil. Stephen realiseert zich pijnlijk dat hij Amelia jaren geleden kende en hij was de enige reden en oorzaak van haar geestesziekte. Hij voelt zich vreselijk schuldig aan zijn verleden en benadert zijn vriend Zachariah John, een wetenschapper. Zachariah helpt Stephen terug in de tijd te reizen en zijn fout te corrigeren die hij onbewust heeft begaan. Stephen gaat naar het verleden in de tijdmachine, verandert zijn verleden en keert dan terug naar de toekomst. Kon hij alles oplossen? Hoe is de toekomst veranderd toen hij zijn tijdlijn veranderde? Wilde hij ooit dat de toekomst op die manier zou gebeuren?
The Eerie Silence: Renewing Our Search for Alien Intelligence
by Paul Davies“Refreshing . . . A penetrating analysis of the assumptions that underlie SETI and the entire enterprise of searching for life beyond Earth.” —Chris McKay, NatureFifty years ago, a young astronomer named Frank Drake first pointed a radio telescope at nearby stars in the hope of picking up a signal from an alien civilization. Thus began one of the boldest scientific projects in history, the Search for Extraterrestrial Intelligence (SETI). After a half-century of scanning the skies, however, astronomers have little to report but an eerie silence—eerie because many scientists are convinced that the universe is teeming with life. Physicist and astrobiologist Paul Davies has been closely involved with SETI for three decades and chairs the SETI Post-Detection Taskgroup, charged with deciding what to do if we’re suddenly confronted with evidence of alien intelligence. He believes the search so far has fallen into an anthropocentric trap—assuming that an alien species will look, think, and behave much like us. In this provocative book Davies refocuses the search, challenging existing ideas of what form an alien intelligence might take, how it might try to communicate with us, and how we should respond if it does.“Paul Davies gives us a panoramic view of the quickening search for cosmic company—a fascinating tale stuffed with novel ideas about the nature of intelligence far beyond our own.” —Seth Shostak, Senior Astronomer, SETI Institute“An immensely readable investigation of the SETI enterprise . . . [A] wonderful book.” —New Scientist“A far-ranging look at what might happen here on Earth when we make first contact. Highly recommended for both science fiction and astronomy buffs.” —Publishers Weekly
Effect-Directed Analysis of Complex Environmental Contamination
by Werner BrackToday more than 5 million chemicals are known and roughly 100,000 of them are frequently used, with both numbers rising. Many of these chemicals are ultimately released into the environment and may cause adverse effects to ecosystems and human health. Effect-directed analysis (EDA) is a promising tool for identifying predominant toxicants in complex, mostly environmental mixtures combining effect testing, fractionation and chemical analysis. In the present book leading experts in the field provide an overview of relevant approaches and tools used in EDA. This includes diagnostic biological tools, separation techniques and advanced analytical and computer tools for toxicant identification and structure elucidation. Examples of the successful application of EDA are discussed such as the identification of mutagens in airborne particles and sediments, of endocrine disruptors in aquatic ecosystems and of major toxicants in pulp and paper mill effluents. This book is a valuable, comprehensive and interdisciplinary source of information for environmental scientists and environmental agencies dealing with the analysis, monitoring and assessment of environmental contamination.
The Effect Evaluation of Haze Governance Policies in Hebei Province–Based on I-O Model
by Guofeng Zhang Xiaojing Ma Huimin LiThis book provides a dynamic simulation model based on input-output table. The model includes an objective function, i.e. maximizing economic and social development and three sub-models, including economic growth model, pollutant emission model and energy balance model. The data of 2012 is selected as the base period data. The haze control policy of Hebei Province is written into the model as an exogenous variable. Reducing the total PM2.5 emissions is an environmental constraint, which is used to eliminate the impact of natural factors on environmental quality. Lingo software is used to simulate this model. By comparing the socio-economic impacts in different scenarios, this book found the most effective policy combination of haze governance. Comprehensive haze governance policy recommendations provide experience for other regions of China and other developing countries. In this book, the dynamic simulation model of haze governance also provides a reference to other environmental policy simulations.This book is divided into five parts. The first part is an introduction. This paper mainly introduces the research background, research status at home and abroad, the purpose and significance of the study, the content and methods of the study, the key scientific problems to be solved and the expected results. In the second part, the current situation and existing problems of economic, social, energy and environment development in the study area are analyzed in detail. In the third part, a comprehensive evaluation model of dynamic optimization of haze control policy is constructed. The fourth part carries on the simulation experiment, and carries on the analysis to the experimental result. The fifth part puts forward the policy suggestions to realize the economic, social, energy and environmental development of Hebei Province.In this book, we have some understandings about haze governance. From the perspective of policy effect, the policy effects of subsidy for soil and water conservation, subsidy for development and utilization of clean energy, subsidy for new energy vehicles, motor vehicle restriction and subsidy for introduction of PM2.5 treatment technology are decreasing. Comprehensive policy can better achieve the goal of sustainable development of economy, energy and environment than single policy, and the effect of "source governance" policy is better than that of "end governance" policy.

Effect of Emerging Processing Methods on the Food Quality: Advantages and Challenges
by Shahin Roohinejad Mohamed Koubaa Ralf Greiner Kumar MallikarjunanThis text comprehensively covers novel, innovative technologies used in the food and beverage industries in order to provide safe and healthy foods for consumers. The research provided in these chapters aims to show that the traditional pasteurization and commercial sterilization of foods result in unacceptable quality and nutrient retention, creating an important need for alternative methods used to minimize undesirable reactions such as thermal decomposition or degradation. Emerging processing methods to minimize heat induced alterations in foods and their applications are covered in-depth, demonstrating that these methods are useful not only for the inactivation of microorganisms and enzymes but also for improving the yield and development of ingredients and marketable foods with higher quality and better nutritional characteristics. Effect of Emerging Processing Methods on the Food Quality: Advantages and Challenges not only covers the advantages of using innovative processing methods, but also the disadvantages and challenges of using these techniques on food quality. Each chapter focuses on a different emerging processing technique, breaking down the sensory, textural and nutritional aspects for different food products in addition to the advantages and challenges for each method. New technologies and advanced theories are a major focus, pointing to innovative new paths for the quality and safety assurance in food products. From pulsed electric fields to ultrasounds, this work covers all aspects of emerging processing techniques for fruits and vegetables, foods and dairy products.
The effect of harvesting and flooding on nutrient cycling and retention in Cyperus papyrus wetlands (IHE Delft PhD Thesis Series)
by Edwin M.A. HesAfrican papyrus (Cyperus papyrus L.) wetlands provide water, food and materials to millions of people, and perform important landscape functions such as water and nutrient storage, habitat provision for fish, birds and other wildlife. They are also an integral part of the culture of African wetland communities. With an increasing demand for food, papyrus wetlands are at risk of conversion to agriculture and losing these ecosystem services. Combining increased agricultural production with wetland conservation is urgently needed. The research presented in this book consisted of two parts. First, field experiments investigated nitrogen and phosphorus retention, showing that papyrus grows faster with disturbance from human activities or flooding, but produces less biomass and stores less nutrients. Then, a dynamic simulation model (Papyrus Simulator) based on the hydrological and ecological wetland processes showed that assimilation, mortality, decay, re-translocation, nutrient inflow and soil porosity were the most influential factors. The model demonstrated that controlled harvesting can increase nutrient retention by up to 40%, but overharvesting leads to the release of nutrients. These findings can help determining optimum harvesting strategies for constructed and natural wetlands, and contribute to the quantification of ecosystem services and an evidence-based adaptive management approach for African wetland landscapes.
The Effect of Hydrogen and Hydrides on the Integrity of Zirconium Alloy Components
by Manfred P. PulsBy drawing together the current theoretical and experimental understanding of the phenomena of delayed hydride cracking (DHC) in zirconium alloys, The Effect of Hydrogen and Hydrides on the Integrity of Zirconium Alloy Components: Delayed Hydride Cracking provides a detailed explanation focusing on the properties of hydrogen and hydrides in these alloys. Whilst the emphasis lies on zirconium alloys, the combination of both the empirical and mechanistic approaches creates a solid understanding that can also be applied to other hydride forming metals. This up-to-date reference focuses on documented research surrounding DHC, including current methodologies for design and assessment of the results of periodic in-service inspections of pressure tubes in nuclear reactors. Emphasis is placed on showing how our understanding of DHC is supported by progress in general understanding of such broad fields as the study of hysteresis associated with first order phase transformations, phase relationships in coherent crystalline metallic solids, the physics of point and line defects, diffusion of substitutional and interstitial atoms in crystalline solids, and continuum fracture and solid mechanics. Furthermore, an account of current methodologies is given illustrating how such understanding of hydrogen, hydrides and DHC in zirconium alloys underpins these methodologies for assessments of real life cases in the Canadian nuclear industry. The all-encompassing approach makes The Effect of Hydrogen and Hydrides on the Integrity of Zirconium Alloy Component: Delayed Hydride Cracking an ideal reference source for students, researchers and industry professionals alike.
Effect of Spaceflight and Spaceflight Analogue Culture on Human and Microbial Cells
by Cheryl A. Nickerson Neal R. Pellis C. Mark OttMany breakthroughs in biological research and translational healthcare advancements have been achieved by studying the response of biological systems to extreme environments. The spaceflight platform provides a unique environment where researchers can explore fundamental questions into cellular and molecular response mechanisms to unveil novel insight into human health and disease. Since the physical force of gravity has shaped the architecture of all biological systems on our planet, spaceflight provides the opportunity to see life in a new adaptational mode - in response to reduced gravity. This enables investigations into the effects of the microgravity environment and associated changes in mechanical forces on mammalian cells/tissues and microbial pathogens, to bring novel insight into disease mechanisms, which are not discernable using conventional experimental approaches. Research using spaceflight platforms represents a paradigm shift in how we observe life processes and is on the leading edge of research discoveries into cellular and molecular mechanisms of health and disease. By incorporating the views of leading authors, this book highlights landmark discoveries and advances in mammalian cellular and microbiology research in both true spaceflight and ground-based spaceflight analogue environments for scientists and students alike who are interested in the influence of physical forces on mammalian and microbial cells, how this impacts transition between normal homeostasis and disease, and basic mechanisms of adaptation to low gravity environments. To provide a thorough understanding of this research, this book covers a range of topics including: (i) description the physical forces interacting with cells in microgravity and microgravity analogue environments, (ii) how alterations in these cellular forces impact human physiology, specifically immune function, (iii) use of these environments to develop organotypic three-dimensional (3-D) tissue culture models as predictive human surrogates for organogenesis and disease research, and (iv) microbial pathogen responses to culture in these environments, focusing on infectious disease Collectively, this information reflects a critical step in preparation for long-duration human space exploration, advances our knowledge of basic biological processes and mechanisms important to understand normal function and disease, and may lead to new strategies for treatment and prevention.
Effect of Sulphide on Enhanced Biological Phosphorus Removal: The Wolfram Language in the Real World (IHE Delft PhD Thesis Series)
by Francisco Rubio-RincónThe enhanced biological removal of phosphorus (EBPR) is a popular process due to high removal efficiency, low operational costs, and the possibility of phosphorus recovery. Nevertheless, the stability of the EBPR depends on different factors such as: temperature, pH, and the presence of toxic compounds. While extensive studies have researched the effects of temperature and pH on EBPR systems, little is known about the effects of different toxic compounds on EBPR. For example, sulphide has shown to inhibit different microbial activities in the WWTP, but the knowledge about its effects on EBPR is limited. Whereas the sulphide generated in the sewage can cause a shock effect on EBPR, the continuously exposure to sulphide potentially generated in WWTP can cause the acclimatization and adaptation of the biomass. This research suggests that sulphate reducing bacteria can proliferate in WWTP, as they are reversibly inhibited by the recirculation of sludge through anaerobic-anoxic-oxic conditions. The research enhances the understanding of the effect of sulphide on the anaerobic-oxic metabolism of PAO. It suggests that the filamentous bacteria Thiothrix caldifontis could play an important role in the biological removal of phosphorus. It questions the ability of PAO to generate energy from nitrate respiration and its use for the anoxic phosphorus uptake. Thus, the results obtained in this research can be used to understand the stability of the EBPR process under anaerobic-anoxic-oxic conditions, especially when exposed to the presence of sulphide.
The Effect of Surface Wettability on the Defrost Process (SpringerBriefs in Applied Sciences and Technology)
by Yang Liu Francis A. KulackiThis SpringerBrief presents a recent advancement in modeling and measurement of the effect of surface wettability on the defrost process. Carefully controlled laboratory measurements of the defrosting of cooled surfaces are used to reveal the effect of surface wetting properties on the extent and speed of frost removal by melting or slumping. The experiments are accompanied by visualization of frost removal at several defrosting conditions. Analysis breaks the defrost process into three stages according to the behavior of the meltwater. Surface wetting factors are included, and become significant when sufficient meltwater accumulates between the saturated frost layer and the surface. The book is aimed at researchers, practicing engineers and graduate students.

Effective and Equitable Teacher Practice in Mathematics and Science Education: A Nordic Perspective Across Time and Groups of Students (IEA Research for Education #14)
by Nani Teig Trude Nilsen Kajsa Yang HansenThis open access book presents original research on effective and equitable teacher practice in mathematics and science education across Nordic countries. It focuses on three key aspects of teacher practice: what teachers teach, how teachers teach, and how teachers assess their students.To provide a comprehensive understanding of teacher practice, data from the IEA’s Trends in Mathematics and Science Study (TIMSS) from 2011 to 2019 was analyzed. TIMSS provides large-scale and representative data, allowing an in-depth investigation of the relations between teachers, their practices, and student outcomes. The findings highlight the changes in teacher practice over time and the extent to which such changes explain the differences in student outcomes. This research also contributes to understanding how the relationships between teacher practice and student outcomes vary across different student groups (i.e., gender, socioeconomic status, and language background). The empirical evidence presented not only adds a significant layer to the academic discourse but also offers practical implications. These insights are crucial in facilitating educational policymaking and classroom practices aimed at improving student outcomes and closing gaps in educational inequality.
Effective Chemistry Communication in Informal Environments
by National Academies of Sciences Engineering MedicineChemistry plays a critical role in daily life, impacting areas such as medicine and health, consumer products, energy production, the ecosystem, and many other areas. Communicating about chemistry in informal environments has the potential to raise public interest and understanding of chemistry around the world. However, the chemistry community lacks a cohesive, evidence-based guide for designing effective communication activities. This report is organized into two sections. Part A: The Evidence Base for Enhanced Communication summarizes evidence from communications, informal learning, and chemistry education on effective practices to communicate with and engage publics outside of the classroom; presents a framework for the design of chemistry communication activities; and identifies key areas for future research. Part B: Communicating Chemistry: A Framework for Sharing Science is a practical guide intended for any chemists to use in the design, implementation, and evaluation of their public communication efforts.

Effective Climate Communication: Turning Eco-Anxiety into Eco-Action
by Anastasia DenisovaThis book explores the urgent challenges of communicating climate change in the media. While many books have been written about climate change, this book goes to the very heart of what makes humans care about stories enough to act. In a direct and sympathetic approach, Denisova tackles problems of greenwashing, news narratives, colonial framings and more. Taking climate anxiety as a starting point, the author positions herself with empathy and asks the question: ‘what slows down citizen action?’ This fresh perspective acknowledges the pressing challenge of public disengagement and the anxiety people feel when faced with increasingly bleak headlines as the climate crisis intensifies. There is a surprising challenge to apocalyptic storytelling and a hero’s narrative, which Denisova argues are counter-productive, while solutions are provided for media storytellers. This book is essential reading for anyone seeking to ease climate-related anxiety and foster a deeper sense of empowerment in their audience.

Effective Ecology: Seeking Success in a Hard Science
by Roger D. CousensEcology is one of the most challenging of sciences, with unambiguous knowledge much harder to achieve than it might seem. But it is also one of the most important sciences for the future health of our planet. It is vital that our efforts are as effective as possible at achieving our desired outcomes. This book is intended to help individual ecologists to develop a better vision for their ecology – and the way they can best contribute to science. The central premise is that to advance ecology effectively as a discipline, ecologists need to be able to establish conclusive answers to key questions rather than merely proposing plausible explanations for mundane observations. Ecologists need clear and honest understanding of how we have come to do things the way we do them now, the limitations of our approaches, our goals for the future and how we may need to change our approaches if we are to maintain or enhance our relevance and credibility. Readers are taken through examples to show what a critical appraisal can reveal and how this approach can benefit ecology if it is applied more routinely.Ecological systems are notable for their complexity and their variability. Ecology is, as indicated by the title of this book, a truly difficult science. Ecologists have achieved a great deal, but they can do better. This book aims to encourage early-career researchers to be realistic about their expectations: to question everything, not to take everything for granted, and to make up their own minds.
Effective Environmental Assessments: How to Manage and Prepare NEPA EAs
by Charles Eccleston J. Peyton DoubAlthough upwards of 50,000 Environmental Assessments (EA) are prepared annually, the focus of the National Environmental Policy Acts (NEPA) Regulations is clearly on defining requirements for preparing environmental impact statements. Surprisingly, until now, there has been no authoritative and comprehensive guide on how to prepare Environmental As
Effective Environmental Emergency Responses: A Holistic Response
by Paul A. EricksonThis book focuses on the variety of subsequent consequences that may follow the conclusion of the immediate emergency response effort, consequences that require multi-disciplinary efforts and most likely may require a revamping of the historical interplay of national and other political authorities. The book is essentially a critique of contemporary emergency response which, in both the public perception and, unfortunately, in the mind-set of many practicing professionals emphasizes an emergency as a singular event. It is a mistaken view: an emergency is actually a sequence of multiple, singular events that unfold over time, sometimes measured in days and weeks and, most often, in months, years and decades. This book focuses on the need, in the current and recent past generation to revamp our thinking about planning for and responding comprehensively to those periodic disruptions to daily routine we call "emergencies".
Effective Evolution Equations from Quantum Dynamics
by Benjamin Schlein Marcello Porta Niels BenedikterThese notes investigate the time evolution of quantum systems, and in particular the rigorous derivation of effective equations approximating the many-body Schrödinger dynamics in certain physically interesting regimes. The focus is primarily on the derivation of time-dependent effective theories (non-equilibrium question) approximating many-body quantum dynamics. The book is divided into seven sections, the first of which briefly reviews the main properties of many-body quantum systems and their time evolution. Section 2 introduces the mean-field regime for bosonic systems and explains how the many-body dynamics can be approximated in this limit using the Hartree equation. Section 3 presents a method, based on the use of coherent states, for rigorously proving the convergence towards the Hartree dynamics, while the fluctuations around the Hartree equation are considered in Section 4. Section 5 focuses on a discussion of a more subtle regime, in which the many-body evolution can be approximated by means of the nonlinear Gross-Pitaevskii equation. Section 6 addresses fermionic systems (characterized by antisymmetric wave functions); here, the fermionic mean-field regime is naturally linked with a semiclassical regime, and it is proven that the evolution of approximate Slater determinants can be approximated using the nonlinear Hartree-Fock equation. In closing, Section 7 reexamines the same fermionic mean-field regime, but with a focus on mixed quasi-free initial data approximating thermal states at positive temperature.

Effective Front-End Strategies to Reduce Waste on Construction Projects
by Peter G. Rundle Alireza Bahadori Ken DoustThis volume outlines a progressively staged process focused on fostering a more effective, more efficient, and greener global construction industry. The research-based book commences with an evaluation of eight methodologies identified after a worldwide literature and compliance review. It is followed by a more detailed report on four of these options, with the ultimate objective of independent selection within the construction engineering community of a single most appropriate methodology as the approach for further, more-detailed investigation. The eight methodologies were selected against six key performance indicators developed as assessment criteria and include knowledge management, lean construction, construction contract procurement practices, optimal work duration on site, construction site waste, rationalization of construction safety regulations, sustainable construction labor force, and portfolio project development. A primary outcome of the selected methodology being a triple bottom-line benefit to key stakeholders, commercially and also to the ecology, along with the community at large. Front-end construction waste strategies to serve as best practices to minimize waste generated by construction projects was the methodology selected for detailed research. The text also covers the primary sources of construction waste. The book is ideal for civil and construction engineers as well as project developers; managers and public sector waste management specialists.
